Among the Label Changes: SPF Claims of More Than 50+ Won’t Be Allowed

FDA Wrapping Up Sunscreen Label Changes

May 21, 2009 -- After years of delay, the FDA is poised to finalize long-awaited sunscreen label changes designed to give consumers a better idea of the sun protection they’re getting.

For the first time, sunscreen manufacturers will be required to provide information on the amount of ultraviolet A (UVA) screening provided by their products. UVA rays do not cause sunburns, but they do contribute to skin cancer and sun-related skin aging.

The new regulation will also prohibit manufacturers from claiming sun protection factors (SPF) of more than 50+, so those very high SPF sunscreens that now line drugstore and grocery-store shelves may go away.

In an interview with WebMD, Rita Chappelle of the FDA confirmed that the agency hopes to finalize the label rules before the end of the year and that SPF claims will be capped at 50+.

But sunscreen companies will have a year to 18 months after the new rules are enacted to make the label changes or provide scientific evidence justifying a higher SPF rating.

Chappelle also confirmed that the terms “sunblock,” "waterproof,” “sweat-proof,” and “all-day protection” will no longer be allowed on sunscreen labels under the new regulations.

“No product can completely block out the rays from the sun and no product is completely waterproof,” Chappelle says. “And labels will have to advise consumers to limit their time in the sun, wear protective clothing, and reapply sunscreen at a minimum of every two hours, especially after swimming or perspiring."

Label Changes a Decade in the Making

It has been a decade since the FDA first proposed a standardized UVA rating system, but there was widespread disagreement about how to best evaluate the level of UVA protection that sunscreens provide.

“It took some time for the science to catch up,” Chappelle says.

Under the new regulations, sunscreens will be subjected to lab and human skin tests using a standardized sun simulator.

Almost two years ago, the FDA unveiled a proposed four-star rating system, with one star representing low UVA protection and four stars representing the highest UVA protection available in an over-the-counter product.
